To all whom it may concern:

Be it known that I, EDW'ARD 'A. FRANKLIN, a citizen of the United States, residing'at Austin, in the county of Travis and State of Texas; have invented anew and useful Machine for Spraying Liquids and Powders-, of which the following'isa specification.

The invention relates to improvements in powder advantageously in theheaviest wind.

The invention consists in the construction and novel combination and arrangement of parts hereinafter'fully described, illustrated in th'e accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 1s a side eleva-' tion-of a spraying-machine constructed in; ac-

cordance with'this invention. Fig. 2' is-a transversesectional view. Fig. 3 is a longitudinal sectional view of the tank or reservoir. Fig. 4, is a vertical sectional view'of the hopper or receptacle. Fig. 5 is a'detail perspective view illustrating the manner of supporting the discharge-tubes. Fig. dis a detail view of the powder-discharging nozzle.

Fig. 7 is a detail sectional view illustrating the construction of the clutch. Fig. Sis a detail view of one of the pumps.

1 designates adrop-axle forming a supporting-frame for the machine and preferably consisting of a transverse bar or beam 2 and depending arms 3, bolted or otherwise secured to the bar or beam 2 near the ends thereof and provided with outwardly-extending spindles 4, upon which'are mounted car Atongue or pole 6 is connected with the bar or beam 2 for the attachmentofdraft-animals, and as the machine is drawn over the surface of the ground by them it is operated as herein described.

One of the carrying-wheels 5 has a geariwh'eel f7 rigidly connected'withits hub; but it may be fixed to the carrying-wheel in any ;other suitable manner.'; This gear-wheel 7,

which is located between the carrying-wheel and the adjacent arm ofthe drop-axle, meshes with a pinion 8 of a horizontal shaftQ, journaled in suitable bearings of the adjacent a'rm 80f the axle, and extending in ward there from. The inner end of the horizontal shaft -9 has a loose-pinion 10 mounted on it, and it is provided with'an annular groove 11, which is inclosed by a key or screw 12 of a clutch-' section 13, also loose on thehorizontal shaft 9. Theclutch-seotion l3, which is fixed to the pinion 10, is adapted to interlock with a sliding clutch-section l hkeyed or otherwise secured to the shaft Sand connected with a shifting lever 15, fulcrumed between its ends and adapted to 1 throw the machine into and out of operation by engaging the sliding clutch-section with and disengaging it from the otherclutch-section.

Thepinion or gear l O meshes with a similar spur gear or pinion 16 of a counter-shaft 17, journaled in a suitable bracketlS and provided at its ends with eccentrics 19. The bracket, which is composed of sides 20 and a transverse connecting portion 21, is provided at the upper and lower ends of the said sides 20 with bearings 22 and 23, and the trans verse connecting portion 21' is bolted or otherwise secured to the bar or beam ZL The lower bearings 23 receive the counter-shaft and the upper bearings 22 receive pivots 24,u pon which compressor-pumps 25 are mounted; The pistons 26 of the compressor-pumps are connected with the pivot-pins of the eccentrics and are reciprocated by the rotation of the counter-shaft, the pivots permitting the compressor-pumps to have the necessary oscillation or play resulting from the direct connection of the pistons to the eccentrics. [The pumps, which are adapted to compress air, are provided at their tops'with check-valves 27 and are connected by flexible conduits 28, such as rubber hose, with an air-inlet pipe 29 of a tank or reservoir 30, adapted to contain water. or other liquid to be sprayed. The'airinlet pipe, which is provided with two exterior arms'orbranches 31, consists of an upright portionor arm 32 and a horizontal portion or arm 33. The upright arm 32 depends from the top of the .tank or reservoir and ex-' tends downward to within a short distance of the bottom thereof, and the horizontal branch or arm 33 is spaced from the bottom and provided wit-h a series of apertures 34, forming jet-openings for the discharge of the air into the reservoir or tank. The horizontal arm or branch of the air-inlet pipe is arranged at the bottom to provide means for agitating the liquid to prevent sediment from collecting at that point. As the machine is drawn along the ground the pumps will be operated and compressed air will be forced into the tank or reservoir, which is provided with a suitable relief-valve 35, which is adj ustablc and adapted to enable the desired pressure to be maintained in the tank or reservoir.

The water or other liquid to be sprayed is introduced into the tank through an opening or manhole, which is normally closed by a cap or cover 36, preferably arranged at the top, as shown. The reservoir or tank is provided at opposite sides of the opening or manhole wlth suitable cocks 37 and 38, having threaded nipples and designed, respectively, for the discharge of air and water. The cock 37 for the discharge of air communicates with the interior of the tank or reservoir at a point above the surface of the liquid, and the cock 38 is provided with a depending pipe 39, extending to the bottom of the tank or reservoir and provided at its lower end with perforations or apertures 40, which are covered by a filter 41, constructed of fine wire-gauze or other suitable material and adapted to prevent the spraying devices from becoming clogged.

The water is discharged through flexible conduits, such as rubber hose, and a segmental nozzle 42 may be employed, as desired, and an atomizer 43 may also be em ployed and may be used simultaneously with the nozzle, if desired. lVhen the atomizer is used simultaneously with the nozzle 42, the water discharged from the cook 38 is divided by a substantially Y-shaped coupling 44 and delivered into two separate tubes 45 and 46. The nozzle 42 is mounted on the outer end of the tube 45, and the other tube 46 is connected with either arm of the atomizer, the other arm being connected with the tube 47, extending from the cook 37. The arms of the atomizer are tubular, and the air and water are simultaneously discharged, whereby the water is divided into a fine spray, as will be readily understood. Instead, however, of arranging the tubes as just described any other desired arrangement may be employed.

The powder is preferably discharged through a substantially T-shaped nozzle 48, connected by a flexible tube 49 with a horizontal tube or passage 50, located beneath and communicating with the hopper or receptacle 51 through an aperture 52 in the bottom of the same. This hopper or receptacle, which is provided with a depending stem 53, is detachably secured to the arm or bracket 54 by means of a set-screw 55 or other suitable fastening device, whereby the hopper or receptacle may be readily removed when desired. Within the hopper or receptacle is arranged a'rotary stirrer or agitator 56, consisting of radial arms 57', provided at their outer ends with shovels or blades 58 and mounted on a transverse shaft 59, journaled in suitable bearings of the hopper or receptacle. The stirrer or agitator by rotating causes the positive and continual discharge of the powder through the aperture 52 at the bottom of the receptacle or hopper, and the size of this opening is controlled to varythe [low of the powder by means of a slide 60, provided with a threaded stem 61, passing through a perforated lug or car and engaged by a nut 62, which is adapted to move the slide in one direction. The slide is moved in the opposite direction by a spiral spring 63, disposed on the stem or screw 61, interposed between the slide and the perforated ear or lug. The shaft. 59, which is extended beyond the hopper or receptacle, is supported by an arm or brace 64 and carries a pulley 65, which is connected by a belt 66 with a pulley'67, The pulley (37, which is rigid with the gear-wheel 10,is controlled by the clutch and the shifting lever heretofore described, and while these pulleys are shown grooved for the reception of the belt yet it Will be readily understood that any other desired form of gearing may be employed for communicating motion from the shaft 9 to the shaft of the hopper or receptacle. The arm or brace 64, which is bolted or otherwise secured'to the transverse bar or beam 2, is provided with a bearing-recess 68 for the reception of the shaft of the hopper or receptacle. The hopper or receptacle is provided with a threaded nipple 69 at the inner end of the tube or passage 50 and is connected with the cock 37 by a suitable flexible conduit, whereby air will be driven through the tube or passage and will cause the powder to be discharged with great force through the T-shaped nozzle 48. The nozzle 48 is provided at the center and at the terminals of its laterals or arms with apertures, so that the powder will be discharged forwardly and laterally.

When the hopper or receptacle is detached, a support or rest 69 may be mounted on the arm or bracket 54. The support or rest c011- sists of a vertical bar or standard secured in the opening of the bracket or arm 54 by the set-screw 55 and provided with a horizontal supporting bar carrying clamps 70. The clamps 7 0, which may be of any desired construction, preferably consist of hook-bolts provided with thumb-nuts and adapted to engage the tubes or conduits adjacent to the nozzles, whereby the latter may be supported in any desired position.

The support or rest ICC 69 may be raised or lowered, and the engaging portions of the clamp may be rotated, as

will be readily understood.

It will be seen that the spraying-machine, which is simple and comparatively inexpensivein construct-ion, is positive and reliable in operation and is adapted to spray either liquid or powder simultaneously or separately with suificient force to enable it to be advantageously employed in the heaviest winds. ihe agitator of the hopper or receptacle is connected with the gearing for operating with the pumps, and the powder is positively and continuously fed to the discharge-pipe. The mechanism for effecting a discharge of powder may be readily removed from the machine, and a nozzleor nozzles maybe supported in any position for the discharge of water. 7
